104 Twenty-Srconp AnNuUAL Report on SvatE CaABrinet, 
CAREX GYNOCRATES var. SUBSTAMINATA. 
Cedar swamps, Jordanville. In this form a single perigynium 
occurs at the base of the staminate spike. Specimens were found 
with the spikes wholly staminate, but none were seen wholly pis- 
tillate. 
Carex scrrporipEA, Micha. 
This rarely produces an additional small spike at the base of the 
principal one. 
Carex siccata, Dew. 
Plentiful on the top of Bald Mountain, Rensselaer county. 
CALAMAGROSTIS CANADENSIS, Beauv. 
Specimens bearing ergot were found at the base of Mt. McIntyre, 
eight miles from any cleared land, from which it is probable that 
the production of ergot is independent of any influence from culti- 
vation. 
This grass grows abundantly in the low grounds and on the 
“beaver meadows” of Essex and Franklin counties, and is cut for 
hay to the extent of many tons. 
ONOoOCcLEA SENSIBILIS var. OBTUSILOBATA, Torr. 
A form closely approaching this rare variety was found in Sand- 
lake by Dr. Howe. The pinne of one side of the frond are more 
contracted than those of the other side; all are sinuate pinnatifid, 
but the pinnules are broadest at the base. The fruit is not well 
developed. 
ASPLENIUM EBENEUM var. IncIsum, Lowe. 
Poestenkill. Howe. In this form the pinne are about one inch 
long, and all except the extreme upper and lower ones are deeply 
incised—pinnatifid ; the pinnules are rather strongly 3-5 crenate 
toothed. I have thought best to give it the name suggested by its 
discoverer. 
TsoETES ECHINOSPORA var. BRAUN, Engelm. 
Poestenkill. Howe. 
SPHAGNUM CYMBIFOLIUM var. concEstuM, Bryol Hurop. 
On all the high peaks of the Adirondack Mts. Its compact 
growth and numerous dense branches probably serve in some meas- 
ure to protect it from the rude assaults of the violent winds to 
which it is exposed. The same mode of growth and dense rami- 
fication is also observed in S. acutifoliwm and other species grow- 
ing in these elevated exposed situations. 
DicraANuM RUFESCENS, Zurn. 
Banks by roadsides. Catskill Mts.
